The Simulator provides several pop-up menus. Pop-up menus are invoked by either clicking on a GUI element (buttons, display etc.) with mouse button 3 (right button) or by a keyboard shortcut of the form <Alt>-<key>.
If you invoke a pop-up menu by clicking a GUI element, its top left corner appears near the mouse pointer. If you invoke the pop-up with a shortcut, the top left corner of the pop-up appears at the bottom left corner of the GUI element.
The following sections described each pop-up menu in detail.
The ON pop-up menu provides functions that are typical for a "File" menu.
Menu item | Shortcut | Description |
---|---|---|
Open program… | Ctrl-O | Open a HP-15C program file. Opens the operating systems standard "Load file" dialogue box to select a file. The new program will override the current program(s) when loaded. |
Save program… | Ctrl-S | Save the current HP-15C program(s) to a file. Opens the operating systems standard "Save file" dialogue box to specify a file. |
Save memory | Ctrl-M | Save the Simulator memory to disk. Path and file name depend on the operating system and can not be changed by the user. |
Load memory | Ctrl-L | Reload the Simulator memory. |
Clear all | - | Set all registers to zero. |
1,000.00 → 1.000,00 | Alt-. Alt-, |
This entry toggles the representation of the decimal point and the decimal separator. |
Preferences… | - | This entry opens a dialogue box that allows you to configure the Simulator. See Preferences for details on configurable items. |
Help… | F1 | Displays the Simulator online help while in RUN mode or the help file for the current program (if available) in PRGM mode. |
About… | - | Opens a dialogue box showing the Simulators copyright, disclaimer and serial number. |
Exit | Alt-F4 | Shuts off the Simulator. |
This menu shows the status of the stack. That is, the values of the numbers stored in each of the four stack registers and in the last x register.
The stack menu is available only in RUN mode, not in PRGM mode.
Selecting one of the menu entries X through T performs a stack roll down. The selected register becomes the X register. Selecting entry LSTx performs a push on the stack and copies the contents of the LSTx register to the X register.
Numbers in the pop-up menu are formatted in the same way as in the display. Let us assume you have keyed in the following:
1 2 ex g √x (or x²)
1 2 ENTER
7 7 7 7 7 7 1/X
4 2
f 7 2 (or simply FIX 2)
When you right click the display, you will see the pop-up menu as shown in the first column:
FIX 2 | FIX 4 | SCI 3 |
---|---|---|
![]() |
![]() |
![]() |
The key sequence f 7 4 gives the format shown in the second column and f 8 3 that in the third column.
In COMPLEX mode, the stack pop-up menu displays both the real and the imaginary stack:
This menu displays the status of the storage registers.
Depending on whether you invoked the menu via the STO key or the RCL key, the menu is either in storage or in recall mode. Selecting a register in recall mode will copy the contents of that register to the X register. In storage mode the contents of the X register is copied to the selected register.
By default, the storage menu is displayed in two-column mode. It can be changed to one-column mode in the Preferences dialogue box.
two-column mode | one-column mode |
---|---|
![]() |
![]() |
As with the real HP-15C the user can change the number of available registers with
f DIM (i).
The pop-up menu will show only the registers currently defined, but a maximum of 20 registers, plus the
I
register. If, for example, the user has limited the number of registers to 3, the pop-up will
look like this:
This menu shows the current program steps in a multi-column list. It is the equivalent of the real HP-15C function GTO CHS # # # (where # = 0…9) which moves the program pointer to the step with the given number.
In PRGM mode the menu is invoked by:
In RUN mode the menu can only be invoked by:
If you select a program step from the menu, the program pointer is positioned on that step. In PRGM mode, the selected program step will also show up in the display.
Three settings affect the layout of the menu (see Preferences).
The following figure shows some examples of pop-up menus:
Code | Code and colour | Mnemonics | Mnemonics and colour |
---|---|---|---|
![]() |
![]() |
![]() |
![]() |
By default, the menu displays coloured mnemonics.
This menu shows the status of the 10 flags.
A value of "1" indicates that a flag is set (on), a values of "0" that it is not (off). The flags 1 through 7 are user-defined flags. Flag 8 indicate whether or not the Simulator is in complex mode. Flag 9 indicates a blinking display.
When you select a menu entry in PRGM mode, the key sequence to inquire the status of that Flag is added to the program. Selecting a menu entry in RUN mode has no effect.
The test menu provides access to the 10 compare operations not directly accessible from the keypad.
The test menu is available only in PRGM mode, not in RUN mode.
The HP-15C has 12 different compare operations. Two of them, x≤y and, x=0, are accessible directly from the keypad. The ten remaining through g TEST n, where n indicates the operations code:
If an error occurs, the HP-15C displays the word "ERROR" followed by the error code. The error pop-up menu provides a decoding for the error numbers.
No. | Short desc. | Description |
---|---|---|
0 | y ÷ 0, LN 0, … | Invalid mathematical operation Invalid argument in one of the following routines:
×, where
x < 0 .1/x, where x = 0 .LOG, where
|x|>1 .cos-1, where in real mode |x|>1 .
STO ÷, where Δ%, where the value in the Y registers is 0.

|
1 | LN A, SIN A, … | Invalid Matrix operation
The Simulator does not support matrix functions. |
2 | Σ Error | Invalid statistic operation

3 | R?, Aij? | Invalid address for register or matrix element
The addressed storage register or the indexed matrix element does not exist. |
4 | LBL?, GTO > MEM, PRGM > MEM |
Invalid line number or label name
Program step addressed by line number is not in use or does not exist (line number > 448).
Attempt to enter more than 448 program steps. Addressed label does not exist. |
5 | > 7 RTN | To many nested sub-programs
More than 7 nested sub-program levels. |
6 | SF > 9, CF > 9, F? > 9 | Invalid flag
Attempt to call a flag greater than 9. |
7 | SOLVE(SOLVE), ∫xy(∫xy) | Recursive call to SOLVE or
∫xy
A program called by SOLVE calls SOLVE;
a program called by ∫xy calls
∫xy. |
8 | SOLVE ? | No root found
SOLVE can not find a root in the given interval. |
9 | ON / × | Service
This error can not occur with the Simulator. |
10 | DIM > MEM | Insufficient memory
Not enough memory to execute the requested operation. |
11 | DIM A ≠> DIM B | Invalid matrix element
Matrix operations are not supported by the Simulator. |
98 | File I/O Error | Error while reading or writing a program file |
99 | Tcl/Tk Error | Tcl/Tk interpreter error This is, of course, no error code of the real HP-15C. Although the Simulator has been tested a lot, there may be some undetected errors in the code.
When you come across such an error, it may happen that even restarting the Simulator does not
solve the problem. In this case, the HP-15C memory file must be deleted manually. |
